After a while playing it matters less how each skill level is named, but I get curious about how long does it take for a soldier to advance from one level to the other. I read a topic about it but still am confused.
How about rank? I have a "rookie" soldier that has 10 missions and 11 kills, and other with 8 missions and 13 kills, but got up to "captain". Why?
Other question, why isn't the "hire list" updated with slightly better soldiers, or just other guys, as time goes by? I propose a separate list with hired personel and other with people available for hire. Now they are mixed on the same list.
